The Discovery Diagnostics tool (**Tools** icon > **Device** > **Discovery** **Diagnostics**) helps Infoblox Technical Support to diagnose discovery and data problems for a given device.

To run discovery diagnostics, do the following:

1. Open the **Hostname ****or ****IP** list and select the target device.
2. Open the **Network**** View** list and choose the network view containing the specified device.
3. If NetMRI doesn't know the community string for the device, enter it in the **Community**** String** field. If NetMRI knows the community string for the device, it is used for the test. If you enter a community string, it is used in addition to the one known to NetMRI.
4. Normally, leave the **Force**** Tests** option set to **Off**. (If the appliance can't run the tests to provide the data needed, this option can be set to **On** to force it to run all tests. Select the **On** option when directed by Infoblox Technical Support.)
5. Click **OK**.
6. When the test is finished, "Processing Completed" appears above the log.
7. Click **TEXT** to save the log.
8. Send the log to Infoblox Technical Support.
